Solar Water Heating is Best Use of Solar Power, Indian Scientists Assert

According to their analysis, published in the International Journal of Global Energy, as the payback time for a solar water heating system is about two years (with a lifespan of 20), this is a far more cost-effective use of solar energy in the developing world than using it to generate electricity. Compared to electrically heated water, solar water heating is 57% of the internal rate of return, the scientists found
